✦ Synopsis


The influence of surface active agents on the rate of dissolution of spherical cap bubbles at Re > 100 is modeled by assuming that the surfactant forms a stagnant film on the spherical surface near the rim of the bubble. The extent of this stagnant zone is dictated by a balance between surface forces and shear forces. The presence of the stagnant zone decreases the rate of mass transfer over the frontal surface of the bubble while transfer across the base is unaffected. Comparison with experimental data shows agreement within 25%.

The mass transfer from a gas bubble in water is calculated for the important case where this mass transfer is decreased by the presence of surfactant in the liquid phase. In the calculation it is assumed that a stationary situation has been established as regards the exchange of surfactant between i

The influence of surface-active agents on the mass transfer coefficient can be classed under three dimensionless parameters: Re, Cu. and De. From this classification, which is represented in a table, it follows whether the interface of the bubble is rigid, free, or of an intermediate nature. The mas
